Mechanism And Control Of Sulphuric Acid Induced Heave in Soils
(2010-07-12)The escalating pollution of the environment has been one of the greatest concerns of science in recent years. Industrial advances in agriculture, expansion of chemical industries and a general change in lifestyle all over ... -
Methodologies for Risk Assessment of Landslides Induced by Rainfall and Earthquake
Landslide is one of the greatest natural catastrophes and poses a major threat to lives and property worldwide. As development expands into unstable hill areas under the pressure of increasing population and urbanisation, ... -
Methods For Forward And Inverse Problems In Nonlinear And Stochastic Structural Dynamics
(2009-09-03)A main thrust of this thesis is to develop and explore linearization-based numeric-analytic integration techniques in the context of stochastically driven nonlinear oscillators of relevance in structural dynamics. ... -
Methods on Probabilistic Structural Vibration using Stochastic Finite Element Framework
(2018-02-07)Analysis of vibration of systems with uncertainty in material properties under the influence of a random forcing function is an active area of research. Especially the characterization based on mode shapes and frequencies ... -
Micromechanical modeling of fracture and fatigue behavior of cementitious composites
The ubiquitous use of concrete as a construction material in the civil engineering industry demands a thorough understanding of its failure process under different types of loading. The composite nature of cementitious ... -
Micromechanics of Wedge and Cone Indentation of Metallic Specimens with Subsurface Voids
Near-surface voids and pores occur in metal parts manufactured by processes as diverse as casting, powder metallurgy, and additive manufacturing. These pores range in size from a few microns to a few mm, depending on the ... -
Mixed Variational Approaches in Nonlinear Continuum Mechanics and Discretization by Finite Element Exterior Calculus
Numerical solution techniques for nonlinear elasticity have been an active area of research for a while. Right from the early days, it was recognized that constructing well-performing FE approximations for nonlinear ... -
Modeling and Analysis of Water Distribution Systems
(2018-01-09)In most of the urban cities of developing countries piped water supply is intermittent and they receive water on alternate days for about few hours. The Unaccounted For Water (UFW) in these cities is very high due to aged ... -
Modeling Of Contaminant Transport Through Soils And Landfill Liners
(2013-04-26)Accurate modeling of contaminant transport and sorption processes in the soil and landfill liners is a prerequisite for realistic model simulations of contaminant fate and transport in the environment. These studies are ... -
Modeling Salinity Impact on Ground Water Irrigated Turmeric Crop
(2018-04-18)Soils in irrigated fields are impacted by irrigation water quality. Salts in the irrigation water may accumulate in the soil depending on amount of leaching, the quality of water and type of ions present. Salinity is an ... -
Modeling the Dependence Structure of Hydroclimatic Extremes
Analysis of extremes in a complex interacting hydroclimatic system is challenging due to rarity of events, small sample size, poor state of data or missing data, lack of statistical tools for analyzing observed changes and ... -
Modelling and evaluation of nitrate transit times in groundwater systems
Transit time distribution is one of the fundamental descriptors of flow and transport behavior of catchments. Intensification of agriculture and consequent anthropogenic inputs of nitrate rich fertilizers in agricultural ... -
Modelling Evapotranspiration from Satellite Data using semi-empirical Models : Applications to the Indian Subcontinent
(2018-05-22)The major aim of this work is to develop a framework for the estimation of Evapotranspiration (ET) over the Indian landmass using remote sensing (RS) datasets in a repeated and consistent manner with improved spatial ... -
Modelling Hydrology of Upper Cauvery Basin Considering Changes in Climate and Landuse/Landcover
In the recent times, changes are noted in hydrological processes (e.g., surface runoff, lateral flow, infiltration, return flow, evapotranspiration, soil moisture and streamflow) in different river basins of the world due ... -
Modelling Multimodal Mode Choice Behaviour with Spatial Variability in Level of Service Attributes
Cities worldwide are grappling with declining public transit usage, primarily due to insufficient spatial coverage of mass transit corridors in sprawling urban regions and inadequate first- and last-mile connectivity options ... -
Modelling Of Single And Multiple Recharge Wells In Layered Aquifers
(2009-05-06)Artificial recharge and rainwater harvesting methods are being applied for mitigating effects of groundwater depletions in severe over-drafting urban and rural situations. When the aquifer to be recharged is situated at ... -
Monitoring and Control of Intermittent Water Distribution Network
Millions of people in low and middle-income countries worldwide receive water only for a small fraction of the time in a day through piped networks. Even though the percentage of the world’s population with access to piped ... -
Monte Carlo Simulation Based Response Estimation and Model Updating in Nonlinear Random Vibrations
(2018-02-22)The study of randomly excited nonlinear dynamical systems forms the focus of this thesis. We discuss two classes of problems: first, the characterization of nonlinear random response of the system before it comes into ... -
